  • the kinetic energy of the pellets is transferred when they hit the surface, directly dislodging residues as in other blasting methods.
  • the thermal shock results from rapid sublimation of the pellets when they hit the surface that has a much higher temperature.
  • the thermal kinetic effect is the result of the rapid sublimation of the dry ice hitting the surface. The combination of these factors results in "micro-explosions" of gaseous carbon dioxide where each pellet impacts.
  • This cleaning process has numerous advantages. It does not damage the surface to be cleaned. It does not release humidity, that may support corrosion. It does not employ a solvent, that may be hazardous. As a primary environmental effect the cleaning process releases, in addition to the residues, carbon dioxide.
